Summary: | The invention discloses a power distribution method for realizing maximum efficiency operation of a fuel cell array. Output voltage and current change conditions of each fuel cell are monitored, operation parameters of each fuel cell are identified on line according to a measured signal, the coordination distribution coefficient matrix is solved based on an iteration method, the reference output power of each fuel cell is obtained in real time, and the purpose of maintaining the fuel cell array to operate at the maximum efficiency point is achieved; and meanwhile, in consideration of the attenuation condition of the performance of the fuel cells along with inconsistent change of the output power, a real-time coding and sequencing mode is adopted to keep the fuel cells with relatively high performance always reach a power peak value firstly through a recording matrix, so that the operation pressure of the fuel cells with relatively poor performance is relieved. The system efficiency of the fuel cell array is m |
